Experiment to unveil dark secrets of the universe

摘要

A method to understand why the universe is expanding and where dark energy comes from has been proposed by a pair of theoretical physicists. The scientists believe creating a 'traffic jam' out of a ring of several thousand ultracold atoms could enable precise measurements of motion. If arranged correctly, these atoms could provide a measurement of gravity at distance as short as 10 micrometres - a tenth of a human hair's width.
